実験手順
Prepared in analogy to example 1 (b) from 2-cyclopentyloxy-5-methanesulfonyl-benzoic acid (Example A4) and 2-piperazin-1-yl-thiazole-5-carbonitrile (Example 6(a)). The crude material was purified by chromatography (SiO2, ethyl acetate/heptane) followed by trituration in ether to yield the title compound as an off-white crystalline solid (yield 64%). MS (m/e): 461.3 (M+H+, 100%).
